Exploring Thomas Kuhn's influential concept of scientific paradigms, this overview delves into the framework of theories and methodologies that guide research. It examines the nature of paradigm shifts, the role of exemplars in scientific education, and the non-linear progression of scientific knowledge. Kuhn's ideas on incommensurability and the impact of social factors on scientific development are also discussed, alongside ongoing debates and critiques of his paradigm theory.

Scientific paradigms are comprehensive frameworks that guide research within a particular field
Determining Valid Scientific Problems
Paradigms dictate what problems are considered valid for scientific investigation
Guiding Scientific Methodologies
Paradigms determine the approach to investigating scientific problems
Paradigm shifts occur when anomalies arise that the current paradigm cannot explain, leading to a scientific revolution
Paradigms pre- and post-shift are so distinct that they cannot be measured against each other using a common standard
Scientists operating within different paradigms face challenges in communication due to the use of specialized terminology and concepts
The choice between paradigms often involves subjective factors and the persuasive power of the new theory
Exemplars are well-established scientific problems and their solutions that act as standard models for problem-solving within a paradigm
Exemplars are central to "normal science," the phase of research that focuses on refining and expanding the existing paradigm
Over time, the collection of exemplars evolves to reflect advancements in knowledge and the essential methodologies for training future scientists
Kuhn proposes that scientific progress involves a series of paradigm shifts interspersed with periods of "normal science."
A new paradigm must address the shortcomings of the old one and retain problem-solving capabilities to be accepted
Kuhn emphasizes the importance of continuity in scientific progress and the ability of new paradigms to resolve existing puzzles

Components of a scientific paradigm
Includes theories, laws, instruments, methodologies guiding research in a field.
01
Role of paradigms in scientific problems
Dictate valid problems and influence approach to investigation.
02
Consequence of paradigm shifts
Results in scientific revolution, changing rules of investigation, often incompatible with old paradigm.
